FTP Sync Download Tree w/ Must-Match Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only for files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

LOCAL lnSuccess
LOCAL loFtp
LOCAL lnMode
LOCAL loSt
LOCAL lnNumFiles
LOCAL i
LOCAL lcRemoteFilename

lnSuccess = 0

* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loFtp = CreateObject('Chilkat.Ftp2')

loFtp.Hostname = "ftp.something.com"
loFtp.Username = "my_login"
loFtp.Password = "my_password"

* Connect and login to the FTP server.
lnSuccess = loFtp.Connect()
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

* Set the current remote directory to the root of
* the tree to be downloaded.
lnSuccess = loFtp.ChangeRemoteDir("/subDir1")
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

* Possible synchronization modes are:
* mode=0: Download all files
* mode=1: Download all files that do not exist on the local filesystem.
* mode=2: Download newer or non-existant files.
* mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
* mode=5: Download only missing files or files with size differences.
* mode=6: Same as mode 5, but also download newer files.

* This example will download all files, but only those files having filenames
* that match *.gif and *.eml

* Imagine our remote directory tree has these files and directories:

* 	accentedLatin1.txt
* 	accentedUtf8.txt
* 	alice.key
* 	anter_cert.pem
* 	chiliPepper.gif
* 	helloWorld.pdf
* 	abc/chiliPepper.gif
* 	abc/ghk/
* 	data/chiliPepper.gif
* 	data/xyz/dkimHtmlBody.txt
* 	data/xyz/dkimVerifyTest.eml
* 	data/xyz/emailForCreateDsn.eml
* 	text/frenchUtf8.txt
* 	text/helloWorld.txt
* 	text/PolishEmailBody.txt
* 	text/something/

* Indicate that we only want to create auto-create local directories (if needed)
* for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
* 1, then the corresponding local directory is created for each remote directory
* traversed regardless of whether files within are downloaded.
loFtp.SyncCreateAllLocalDirs = 0

loFtp.SyncMustMatch = "*.eml; *.gif"
lnMode = 0
lnSuccess = loFtp.SyncLocalTree("c:/temp/subDir1",lnMode)
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

lnSuccess = loFtp.Disconnect()

* Show the files downloaded.
loSt = CreateObject('Chilkat.StringTable')
loFtp.GetSyncedFiles(loSt)

lnNumFiles = loSt.Count
i = 0

DO WHILE i < lnNumFiles
    ? loSt.StringAt(i)
    i = i + 1
ENDDO

* Output showing the files downloaded:

* chiliPepper.gif
* abc/chiliPepper.gif
* data/chiliPepper.gif
* data/xyz/dkimVerifyTest.eml
* data/xyz/emailForCreateDsn.eml
